# VIC: Winning Strategies

by Texas Instruments

#### Objectives

Students are able to explore and investigate correlation strength: Strong / Moderate / Weak, nature: Positive / Negative and form: Linear / non-Linear visually and later, quantitatively using Pearson's Correlation Coefficient. Students are also instructed to combine collections of statistics with a view to identifying stronger correlations. To illustrate their understanding, students are posed a challenging problem to place an imaginary team into the appropriate ladder position, based on a selection of statistics. Students need to consider the strength of the previously computed correlation for each of the provided statistics and how helpful that might be in predicting the team's ladder position.
